These plants each have their own quirks. The Venus Flytrap snaps shut on its prey, while Sundews use sticky hairs to trap insects. If you’re just starting out, Sundews and Butterworts are pretty low-maintenance. But if you’re up for a challenge, try the Australian Pitcher Plant.

No matter which plant you choose, make sure your terrarium setup is just right. Check out our guides on terrarium plants for beginners and best plants for closed terrariums. And if you want to mix things up, consider adding moss for terrariumssucculent plants for terrariums, or ferns for terrariums.

Terrarium Suitability

Carnivorous plants bring a touch of the wild to your terrarium. But to keep them happy, you need to know what they like.

Venus Flytrap Care in Terrariums

Venus Flytraps

Venus Flytraps (Dionaea muscipula) are the rock stars of the carnivorous plant world. They come from the subtropical wetlands of North America and love warm, humid conditions with lots of sunlight. They need a winter dormancy period, which can be tricky in a terrarium. They munch on small insects like spiders and gnats, which you can introduce or let them catch on their own.

Care Requirements:

  • Bright, indirect sunlight
  • High humidity
  • Acidic, nutrient-poor soil
  • Distilled or rainwater only

Australian Pitcher Plant

Australian Pitcher Plant


The Australian Pitcher Plant (Cephalotus follicularis) is like the pitcher plant’s cool cousin. It has pitchers that range from small cups to big vases, perfect for trapping insects. It needs bright light, acidic soil, and regular watering. It does best in humid conditions but not too wet, to avoid rot.

Care Requirements:

  • Bright light for at least 6 hours a day
  • Sphagnum moss or a peat-based soil mix
  • Regular watering to keep soil moist
  • Occasional feeding with small insects

Sundew Care and Benefits



Sundews (Drosera spp.) are like the sticky traps of the plant world. Their leaves are covered in sticky, dew-like droplets that lure and trap insects. They’re great for pest control and even help purify the air in your terrarium. They like bright light and consistent moisture.

Care Requirements:

  • Bright, indirect light
  • High humidity
  • Wet, acidic soil
  • Minimal feeding since they catch their own prey

Terrarium Considerations

When setting up a terrarium for carnivorous plants, you need to think about their specific needs, the right container, and the best species for your setup.

Carnivorous Plant Terrarium Requirements

Carnivorous plants thrive in low-nutrient environments. They need bright light, high humidity, and pure water like distilled or rainwater. Recreating a boggy, nutrient-poor habitat is key to their survival. Your terrarium should provide plenty of light and the right moisture levels.

Container Choices for Carnivorous Plants

The container you choose can make a big difference. Open containers let the plants catch their own prey, while closed containers mean you’ll need to feed them. Pick a container that matches your level of involvement.

Recommended Carnivorous Plants for Terrariums

Not all carnivorous plants are terrarium-friendly. Sundews and Pitcher Plants are great for humid conditions, while Venus Flytraps and Sarracenia might struggle in confined spaces.

  • Sundews (Drosera): Bright light, high humidity, sticky leaves for trapping prey.
  • Pitcher Plants (Nepenthes/Sarracenia): High humidity, pitfall traps, good for larger terrariums.
  • Butterworts (Pinguicula): Small spaces, sticky leaves for trapping insects.
  • Bladderworts (Utricularia): Aquatic, good for terrariums with water features.

Terrarium Soil and Setup

Creating the perfect home for carnivorous plants means getting the soil mix and setup just right.

Soil Mix for Carnivorous Plant Terrariums

Carnivorous plants need well-drained but moist soil with low nutrients. Here’s a good mix:

Material Purpose
Peat Moss
Moisture retention, acidity
Coco Coir
Moisture retention, resists fungi
Sphagnum Moss
Aeration, moisture retention
Drainage, aeration
Drainage, prevents compaction
Structure, aeration

Avoid fertilizers and compost, as they can harm these plants.

Terrarium Setup for Carnivorous Plants

Setting up a terrarium involves layering materials to create the right environment:

  1. Drainage Layer: Use lava rock at the bottom to prevent water-logging.
  2. Soil Layer: Add nutrient-free soil like peat moss or coco coir.
  3. Top Layer: Finish with live sphagnum moss for humidity and moisture control.

Proper layering keeps roots from sitting in water, preventing rot while providing moisture.

Terrarium Lighting Options

Good lighting is crucial. Here are two popular options:

Lighting Type Benefits Lifespan Energy Efficiency
Fluorescent Grow Lights
Affordable, decent spectrum
LED Grow Lights
Energy-efficient, long-lasting

Fluorescent lights are budget-friendly, while LEDs are a long-term investment.

Terrarium Types

Ornamental Terrariums for Carnivorous Plants

Ornamental terrariums are a stylish way to show off your carnivorous plants. You can plant them directly in the substrate or keep them in pots within the terrarium. These setups are great for smaller plants like sundews or butterworts.


  • Enclosed glass structure
  • Suitable for individual plants
  • Can accommodate potted plants
  • Ideal for smaller species

Open Terrariums for Carnivorous Plants

Open terrariums let your plants interact with their environment. They don’t have a lid, so temperature and humidity match the room. This setup is good for trapping house pests and offers a clear view of the plants.


  • Lidless design
  • Ambient room conditions
  • Direct exposure to the environment
  • Good for trapping house pests

Fish Tank Terrariums for Carnivorous Plants

Fish tank terrariums are versatile and great for larger plants like Nepenthes. They can be modified for high humidity and temperature control, providing ample space for a diverse plant collection.

Nutritional Needs

Carnivorous plants are unique in how they get their nutrients. Understanding their needs is key to keeping them healthy.

Carnivorous Plants and Nutrient Acquisition

Carnivorous plants thrive in nutrient-poor environments. They’ve evolved to catch insects to supplement their diet, especially for nitrogen, phosphorus, and calcium. In places like Quebec’s acidic peat bogs, these plants have adapted to get what they need from their prey.

Specific Nutritional Needs of Carnivorous Plants

Each type of carnivorous plant has its own nutritional quirks:

  • Venus Flytraps: Use snap traps to catch insects, need nutrient-poor soil.
  • Sundews: Sticky tentacles trap insects, need consistent moisture.
  • Pitcher Plants: Tube-like leaves trap insects, need a peat and sand mix.

Meeting Nutritional Requirements in Terrariums

In a terrarium, you need to mimic their natural conditions. Here’s a quick guide:

Plant Type Substrate Insect Feeding Enzyme Presence
Venus Flytrap
Nutrient-poor, well-draining
Evenly moist, well-draininRequired g
Poor in nutrients, consistent moisture
Pitcher Plant
Peat mixed with sand
Not strictly required

Creating the right environment involves choosing the right soil and lighting. For more on setting up your terrarium, check out our guides on terrarium soil and setup and lighting options.
